GÉANT and DECIDE: Improving quality of life
for sufferers from Alzheimer’s Disease
Using advanced networks and grid computing technology to
enable earlier diagnosis and faster treatment for patients
Dementia – the growing challenge for healthcare
Over 35 million people around the world suffer from a form of
dementia, with 7.3 million in Europe alone. This number is predicted
to double over the next 20 years to 65.7 million sufferers by 2030.
With no current cure for dementia conditions such as Alzheimer’s
Disease and schizophrenia, the medical focus is on earlier diagnosis,
which dramatically improves the quality of life for both patients and
their carers, as well as research into the causes and prevention of
these crippling diseases.
However early diagnosis is often difficult, as many of the symptoms
of Alzheimer’s can be confused with common signs of aging. A user-
friendly way to help make an informed diagnosis is therefore vital.
To achieve this clinicians need to analyse the rapidly increasing
amount of patient data, such as medical images from Positron
Emission Tomography (PET), Magnetic Resonance Imaging (MRI), The Challenge
Computerised Tomography (CT) and Electroencephalography (EEG) Worldwide, dementia is one of the fastest growing medical
